You may be wondering what diffusion‚ tonicity‚ osmosis and semipermeable membrane is. I’ll start off by explaining semipermeable membrane. A semipermeable membrane relates to the dialysis lab #1 because in dialysis tubing is considered semipermeable barriers. Semipermeable membrane is a membrane that allows passage of some particles but not others. (Lab manual) Diffusion on the other hand‚ is a form of passive transport where particles move down their concentration gradient from a region of high

The patient cannot work regularly because of his dialysis treatment schedule. His mental and physical state has progressively deteriorated to the point that the patient has threatened to commit suicide if he has to remain indefinitely on dialysis. In an effort to help her husband‚ the patient’s

Do we love our pets too much? My ten year old pitbull mix was having problems with her hips. She barely got up‚ but when she did‚ she would skid on the floor. From doing so‚ she had scrapped off a piece of her skin on her forearm. It got infected after we would clean it and wrapping the wound‚ she wouldn’t stop opening it. She eventually couldn’t get up anymore. We all knew it was her time to go. According to Burkhard Bilger in his essay “The Last Meow” in the New Yorker‚ he explained what people

Raisha Miggins Lab 5: Osmosis Purpose The purpose of this lab was to explore the concept of Osmosis using dialysis tubing and different concentrations of sucrose solutions‚ and to help one better understand what happens to cells when they are exposed to solutions of differing tonicities. Hypothesis If the four dialysis tubes containing different concentrations of sucrose are all placed in their appropriate solutions for 20 minutes‚ then my predictions are as follows: The 1% in 1% sugar solution

the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells. In experiment 5.1 in order to observe diffusion we examine the Brownian movement by observing carmine on a wet mount slide‚ and by using dialysis tubing‚ we investigate the selective permeability to reducing sugar‚ glucose‚ starch‚ and iodine potassium iodine. In experiment 5.2 we use samples of ox blood and Elodea plant to observe the net flow of water from the surrounding solution into the
